ALWAYS MAINTAIN PROPER CONTROL OF THE
SURFACE PLANER. IF AN OPERATOR LOOSES
CONTROL OF THE MACHINE, A “RUNAWAY”
SURFACE PLANER CAN RESULT IN PROPERTY
DAMAGE AND/OR PERSONAL INJURY. BECAUSE
OF THE UNIQUE OPERATING CHARACTERISTICS
OF THE SURFACE PLANER, THERE IS NO
PROVISION FOR THE ELECTRIC MOTOR/ENGINE
TO AUTOMATICALLY STOP IF THE OPERATOR
FAILS TO MAINTAIN PROPER CONTROL.
WHEN OPERATING THE SURFACE PLANER ON
ABOVE GROUND LEVELS, EXERCISE EXTREME
CAUTION TO PREVENT LOSS OF CONTROL THAT
COULD ALLOW THE MACHINE AND/OR OPERATOR
TO FALL DOWN TO LOWER LEVELS. SUCH AN
OCCURRENCE CAN RESULT IN PROPERTY
DAMAGE AND/OR PERSONAL INJURY.
6) beam and pentagonal flail are bi-directional in
design and can be operated in both forward and
reverse directions. Milling flails are one directional in
design. This limitation requires the operator to install
a loaded drum on the driveshaft with the tungsten
carbide inserts facing the direction of rotation. FIGuRE
25. Remove work surface material only by pulling the
Surface Planer towards the operator after the drum has
been lowered to the desired cutting depth. Never push
the Surface Planer forward when the milling flails are
in contact with the work surface material.
This technique will allow the following to occur:
a) The milling flail “hammers” rather then “cuts” the
material, producing ineffective results and substantial
lower productivity.
b) Flail body material is subject to accelerated wear,
especially in the area supporting the tungsten carbide
insert. As this area wears, the insert becomes chipped
and can “break off” from the flail body, thus significantly
reducing its efficiency and useful service life.

7) The maximum cutting depth on a slab surface is 5/8
inch. It is not recommended that the Surface Planer
be utilized to achieve depths greater than this value.
In most operating configurations, the normal planing
depth per single pass will vary between 1/16 to 1/8
inch deep depending upon the work surface material
type and flail type and/or configuration. This planing
depth range will usually maximize productivity rates
and component service life.
8) For normal job applications, operate the engine at a
maximum, governed speed of 3450 RPM. Consult the
material supplied by the engine manufacturer and the
Specifications section for specific information.
9) The planing process on many work surface materials
can produce sparks, dust and other foreign particle
contamination.
SPARKS PRODUCED BY THE ACTIONS OF
THE FLAILS IMPACTING AGAINST THE WORK
SURFACE (FOR EXAMPLE: STRIKING ANCHOR
BOLTS) DURING THE PLANING PROCESS MAY
COME IN CONTACT WITH MATERIALS THAT
CAN RESULT IN A FIRE AND/OR EXPLOSION.
THIS OCCURRENCE CAN RESULT IN PROPERTY
DAMAGE AND/OR PERSONAL INJURY.
THE CREATION OF DUST AND OTHER
FOREIGN PARTICLE CONTAMINATION FROM
THE OPERATIONAL PROCESS CAN RESULT
IN PROPERTY DAMAGE AND/OR PERSONAL
INJURY.
